WebFrom earlier photometric observations [3], a regular outburst cycle of roughly 22 days has been reported for V363 Lyr, associated with almost symmetrical rise and fade phases of the light curve. The increase in brightness from minimum to maximum has been measured to be of the order of 3 magnitudes or slightly more. WebQuestion 2: The light curve for a variable star is shown in the figure to the right.a) Identify the type of variable star and explain your criteria for classifying itas such, b) estimate the depth of the primary (deeper) eclipse, and c) describe what you can conclude about the period of the variable from looking at the light curve. how are evaporite rocks formed
